Manchester United are eyeing a deal for midfielder Fred if they can reach agreement with Shakhtar Donetsk, sources have told ESPN FC.

Manager Jose Mourinho is looking to bolster his midfield after Michael Carrick's retirement, with 25-year-old Fred, who will be part of Brazil's World Cup squad, one of the names on his list.

Mourinho is also interested in Tottenham centre-back Toby Alderweireld and Chelsea winger Willian.

Sources have told ESPN FC that Tottenham are willing to listen to offers for Alderweireld, with the Belgium international so far refusing to sign a new contract.

Willian's situation at Chelsea is more complicated, and sources have told ESPN FC the winger would be open to a move to Old Trafford -- but Chelsea do not want to lose another player to United after criticism following the sale of Nemanja Matic.

United have also handed England Under-17 captain James Garner his first professional contract.

The highly-rated midfielder, 17, was part of the U18 team that won the Northern Premier League title this season.
